Who uses a torque wrench for spark plugs?

Yep. Probably the biggest factor of all...... A lesson I learned on air cooled VW motors.

 

Oddly enough I learned this on my 98 GTI VW VR6! Lol The plugs were always tight when warm and easy to come out the next day never buggered it up but figured it out real quick... Still miss the crazy exhaust sound of that motor... Also owned a 1st Gen Taurus SHO with the Yamaha motor between those two I have never owned another NA V6 that has come close to sounding as good... Ahh the good old days...
